Yes, some of the older Vectors with a "floating mid-flap" did have main lines entangle with the middle of the rig. Neither of these two instances were fatal or even injury related, however they were scary. That was several years ago, and as a UPT Vector pilot for many years, I am not concerned. They have addressed the possibility in newer models. I have tested up to six feet, and have extended the experiment to an entire DZ in Canada, Edmonton Skydive Centre, and they have reported nothing but improved openings.

I am not suggesting that you extend the unstowed length to six feet. I am merely working to prove the point that there is no increased danger associated with two or three feet of unstowed line above the risers. There is however, a very real and provable risk to stowing less than two feet. Linetwists can be severely unpleasant. Check out this video on YouTube:
